HEEL ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 22, 1918.

Application filed February 13, 1917. Serial No. 148,865.

To all whom it may concern:

Be it known that I, CHARLES HAROLD HELME, a citizen of the UnitedStates, residing at Portland, in the county of Cumberland and State ofMaine, have invented certain useful Improvements in Heel Attachments, ofwhich the following is a specification, reference being had therein tothe accompanying drawing. I

The invention relates to a heel attachment, and more particularly to theclass of heel calk attachments for the heels of boots, shoes, or thelike foot wear.

The primary object of the invention is the provision of an attachment ofthis character wherein the heel of a boot or shoe is materiallyreinforced, so as to prevent the heel from crushing or materiallywearing away at the edges thereof, therebyincreasmg the life of theheel.

Another object of the invention is the provision of an attachment ofthis character wherein the outermost lift or ply of the heel ismaterially reinforced, so as to increase the wear of the heel, andthereby sustaining the same straight, thus obviatin the running over ofthe heels of boots or s oes, as is usual.

A further object of the invention is the provision of an attachment ofthis character wherein the entire heel, irrespective of the materialfrom which the same is made, is materially strengthened, so as to giverigidity thereto, and thereby avoid the breaking down of the same, so asto assure neatness thereto, and avoid the running over of the heel, orthe shoe becoming out of shape resultant therefrom.

A still further object of the invention is the provision of anattachment of this character which possesses simplicity in construction, reliability and efliciency, durability, strength, and also onewhich is inexpensive in manufacture.

With these and other object in view, the invention consists in thefeatures of construction, combination, and arrangement of parts, as willbe hereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary bottom plan view, showing a shoe heel by fulllines, and the attachment constructed in accordance with the inventionapplied, by dotted lines.

Fig. 2 is a fragmentary vertical longitudinal sectional view of the heelplate.

Fig. 3 is a perspective view of the heel plate.

Fig. 4: is a perspective view of one of the calks.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, A designates generally a shoe heelwhich is usually made up from a plurality of plies 5, preferablyleather, although the same may be made from any other substitutematerial, the said heel being constructed in the usual well knownmanner, and is merely shown to illustrate the application and manner ofuse of the attachment hereinafter fully described.

The ply 6, next to the outermost ply 7 of the series 5 of the heel, iscut to form a counter-sink 8 for receiving a frame 9, forming areinforcing plate, which is preferably made from metal, and is providedwith an open center 10, which may be of the required shape and whichserves as a cell between the outermost ply 7 and the ply 8 next theretoof the heel, thereby assuring a determined amount of resiliency totheheel.

Mounted in the heel A, through the inner face thereof, is a series ofcalks, each comprising a stem 11, formed with a head 12 at one end,while the opposite end is reduced to form a rivet terminal 13, and thesecalks are inserted within the heel A in suitable openings therefor,formed in the plies 5 of said heel from the inner side thereof, theheads 12 being fitted in correspondingly shaped counter-sinks 14: formedin the innermost ply, while the reduced ends 13 are passed throughapertures 15 formed in the frame 9, and are riveted thereto prior to thefastening of the outermost ply 7 in place, as will be clearly obvious,the counter sink 8 is correspondingly shaped to the plate 9 foraccommodating the same, which is concealed by the outermost ply 7 of theheel when said ply is fastened in place, as is clearly shown in Fig. 2of the drawing.-

The heads 14 of the studs abut and contact with the heel end of the soleB of the shoe, as is also clearly shown in Fig. 2 of the drawing, and bythe use of these studs and the plate of frame 9, the heel of said shoeis materially reinforced, and is pm, vented from breaking down.

It Will be noticed that substantially four studs are employed and thesestuds are arranged adjacent to the rim of the heel as is clearly shownin Fig. 1. The pressure applied by the foot down upon the heel of theshoe is transmitted to all of the studs and the shoulders of said studsapply a downward pressure on the plate 9 which is fiat and stiff andtends to keep the heel in engagement with the surface it engages.

Numerous modifications may be made in practice without departing inprinciple from the details of construction herein disclosed.

What is claimed is:

In a shoe, in combination, a plurality of leather heel layers, theinnermost layer being formed at its four corners with countersunkoutwardly flaring recesses, the next to the last layer being formed witha countersunk cavity, a heel-shaped plate formed with a largecentralopening so as to provide a perimetrical strip of uniform width,said plate being formed with four relatively small openings, and fittingsnugly within the cavity of said second mentioned layer, arseries oflocking bolts each consisting of a conical head embedded in one of saidfirstnamed recesses, and a main body portion projecting into allot-saidlayers andtermt nating in a reduced :portion' projecting through'one ofsaid small -openings, and be-' leather layer securedso :as to overlapand" Copies of this patent may be obtained for five cents each, .byaddressingthe-'ficommissioner :olriEatentu Washington, D. 0.
